Former Yemeni President Ali Abdullah Saleh was admitted Sunday to a military hospital in Sanaa , the second time that he 's been to a hospital this month , a government official said .

Saleh led Yemen for 30 years before stepping down , amid widespread protests as well as international pressure , last November as part of a long discussed deal brokered the six-nation Gulf Cooperation Council .

He suffered extensive burns and a collapsed lung in a June 2011 strike on the mosque in Yemen 's presidential compound , a U.S. government official said then . In subsequent months , he has gotten continued medical treatment in various places , including in Saudi Arabia and New York .

The Yemeni official said Sunday that Saleh was in the hospital for `` a scheduled checkup , not an emergency , '' while acknowledging he continues to face health issues .

There are `` concerns from Saleh 's staff that he still needs more medical procedures and treatment , '' the government official said .

Since leaving office last year , Saleh has remained a force in Yemeni politics . That includes threatening this March to withdraw all members of the nation 's ruling party , which he still heads , from the national government and warning Prime Minister Mohammed Saleh Basendowah he could face imprisonment .

The leaders of the current government have expressed support for extensive reforms , while Basendowah attended a ceremony at Change Square in Sanaa and condemned the old regime 's attacks against unarmed youth protesters .

U.S. President Barack Obama issued an executive order last Wednesday targeting `` those who threaten the peace , security , or stability of Yemen , '' including by obstructing implementation of the transition agreement .

The new order allows the U.S. Treasury Department to freeze U.S.-based assets of anyone who might subsequently be listed under the order . While no specific entity was named , it is widely believed to be aimed at the former president 's circle .
